    Radio upgrade?

    Which one did you get? Did you have to get a wheel control module like the maestro?

    How can the odometer be changed from displaying kilometers back to miles and vice versa?

    If I had a steering wheel with controls connected to the harness in the Tahoe, would that work or would I need a different BCM?

    How can the odometer be changed from displaying kilometers back to miles and vice versa?

    I have a tech 2. I was in the BCM menus and found the instrument panel sub menu, from what I can see you can test most things and get displayed vs sensor readings from the ECU, can see the lag time in real time, turn on all dummy lights. I can view instrument cluster reported transmission temp...

    How can the odometer be changed from displaying kilometers back to miles and vice versa?

    The vehicle in question is an '05 Avalanche with steering wheel controls. The other one is an '03 Tahoe LS without steering wheel controls. Is there any way to change that one?

    A previous owner changed it and I want to switch it back, what is the best way to do it?

    Np 246 pinout?

    Oh yea. NGL, I'm worried about that.

    Np 246 pinout?

    It looks like the encoder sensor is just fine, same with the motor, but all three gears are damaged.

    Np 246 pinout?

    Alright! The encoder motor I bought from Amazon was only $106 all in. That fixed it. I'm pretty sure the encoder I removed was from a junk yard, as all the external screws were painted pink. I also took photos of the encoder return voltages after the new one was in. More photos in the next reply.

    Np 246 pinout?

    Oh yea I saw the speed sensor data, all zeros.

    Np 246 pinout?

    Interesting. I think I'm going to go over the disconnected harness, including output shaft and front speed sensor harnesses. Oh ok, gotcha. Have you tested the speed sensors before, or changed them? I'm waiting on a new encoder motor to get here and my garage is full...and the weather is bad so...

    Np 246 pinout?

    I found a good writeup on the avalanche forums, the motor lock circuit, when de-energized (disabled in tech 2) actually LOCKS the encoder motor in it's current gear selection. When showing ENABLED in the tech 2, that energizes the circuit and the lock is turned OFF. Only during gear change...

    Np 246 pinout?

    Yea. The 2003-2006 is unique, but mostly similar to the previous iteration, in functionality. NBS is 5V ref. and has motor A/B simplified control vs the older system. I'm ordering an encoder motor assembly...if that fixes it, I may tear down my old one to maybe figure out the differences.

    Np 246 pinout?

    Hmm, some colors are sure to match up, or that is at the TCCM? At the encoder motor on the tcase, it's an 8 pin connector utilizing 7 pins. RED, ORANGE, TAN and BLACK are 12 or 14 gauge, with a dark blue/white, brown/white and green/black 20 gauge wires. The connector pins and wires coming off...

    Np 246 pinout?

    Hey does anyone have the encoder motor pinout for the 246? 2003 if year matters. My tccm doesn't throw codes, the pushbutton control responds to shift requests, which is also evident on the tech 2 data page. Shees stuck in 4hi, and the only mode it goes to is 4wd auto, but the SUV always starts...
